V bottles and the like. It has been found desirable to place over themouths of milk and similarbottles, to protect the pouring edge thereof, a suitable cap 'covering retained in position by holding means, which latter is removed by the housewife when it is desired to lift' the cap or cover from the bottle' mouthr and pour the contents from the bottle. The holding means now employed are lobjectionable, as in most instances they require a tool or prying implement to release the same and often remain onthe neck of the bottle when it is washed by the housewife and returned to the distributor for refilling. The failure to completely Aremove the holding means from the bottle necessitates the dairy, distributor, or filling station, as the case may be, maintaining an attendant or operator for this purpose, and entails considerable expense both in labor and in loss of time.

The present invention has for its principal object to `provide a form of cap holding means, which, when in position, will securel hold the cap in position over the bottle mouth, and which is capable of ready removal'by the housewife without the necessity of tools or implements, and when released from the bottle cap, is also severed from the bottle. Another object is 'to provide a means of the above type which is adaptable for ready disposal by the housewife, is extremely inexpensive in its application and use, and is also eiicient for the purpose intended. v

To those skilled in the art of bottle capping, particularly of milk-bottle type having a skirted cap, it is well known that the cappingis done by machinery, the bottles filled with milk passing through the filling and capping machine at a very rapid rate of speed. For this reason it is not possible to give detailed individual treatment to each bottle, and therefore the sealing means must be simple, quickly applied and be certain of holding. For vthis reason lthe plurahty of wrappings accom lishes a new result 1n a new way, in that t e stress or tension exerted on the cord ends is absorbed in the plurality of wrappings and not upon the'sealng me- 1927. Serial No. 184,590.

dium, the. result of such structure being that the sealing medium has practically no stress thereupon during the period it is drying, coagulating, or otherwise adhering to the cord to securely position the cord ends. This, thereforepermits passage of bottles through the capping machine at a very high rate of ,speed with practically no inspection and insures a very simple, efficient and inexpensive means to securely hold lor maintain the skirted cap over the bottle.

The lnvention consists broadly in wrap'- ping or wlnding a cord, tape, paper, twine,

-wire or other flexible element, either elastic or nonelastic, a plurality of times about the W skirt of a bottle cap to hold the same in position on the bottle mouth, crossing or lapping the ends of the element and securing the wrappings together at their point of crossing or at one or more points within their length by the application thereto of sealing wax, or other material capableof easy application and preferably fragile when set; to prevent the releasing of the wrappings, and with the y ends of the material lying free and of a length to afford a grip being had thereon whereby the securing means may be readily fractured, or broken, or torn, releasing the iiex-` ible element on one ofthe ends thereof being grasped and manipulated to fracture or disrup't the securing or sealing means.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the acu companying drawings, and set forth in the claim hereto appended, it being .understood that various changesin the form, proportion, size and minor details of construction within the scope of the claim may be resorted to 90 without departing from the spirit or sacrificing any of the advantages of the invention.

Referring to the drawings forming part of the present application g5 Fig. 1 is a view in elevation of the preferred embodiment of my invention as applied to the skirt of a sealing cap for the conventional type of milk bottle.

Fig. 2 is an enlarged detail view of a por- 100 tion ofthe element at the point of overlap of `its ends.l

Fig. 3 is a View Similar to ingle with'the Sealing means applied.

'5 vReferring to the drawings wherein .like

characters of reference designate corresponding parts, l indicates the neck of a conventional milk bottle, over the mouth andthe upper pouring edge of which vis positioned a 10 sealing cap of any of the conventional types, having a skirtB preferably pleated at3'.. en'- abling the same to be tightly drawn into-con-` tact with the outer surface of the bottle neck 4. y f -V A flexible member 5 is wrapped or wound under tension a plurality of times around the skirt 3, and at one or more places the wrappings where lthey extend beyond each other, arefsecured together bythe application of 20 sealing wax, shellac, or other substance or element 6. I prefer a substance which is readily fracturable when the same hardens or sets' on the application thereto of a pressure less than @the breaking-strain of the flexible fmember,

scribed, it is understoodthat a disk orV sheet of fiexible'material may equally aswell be employed. The Apreferred-point of application of the substance or element 6, as illus- .80 trated in-the drawing, is where' the terminal is desired to releasethe flexible element from y its osition around the cap skirt.

ith the capl in position as in the drawings, and the member 5 retaining the same in posimeans thus preventingthe unwinding .or unwra-pping of the member 5, the housewife or operator to release the cap grasps one of the and While a plasticelement'is shown and de- `tion, against the bottle neck 4,the sealing illustrated in the drawings that the sealing means engages each wrapping and unites one to the other. The multiple wrapping of the member 5 about the skirt also reduces the period required for holding the member 5 under tension until the sealing means hardens, thickens, dries or congeals sufficiently to tightly retain the wrapping member in place.

I claim z- A bottle-closure having adepending skirt ortion adapted to enclose the mouth of a ottle, a continuous 'flexible cord wrapped a plurality of times around said skirt portion and having its ends releasably positioned and 'a sticky sealing'medium applied in a substantially sticky state to the releasably positioned end portions of said cord.

ends'? of the member 5, either end being available for this purpose, and manipulates the same by pulling itoutwardly away from the skirt or toward'thesealin means or 'element 6 with sufficient force to racture or tear the sealing means permitting the releasing or unwinding of the member, 5 from the cap skirt lea-ving the cap free forready removal from the bottle mouth. Then when the memv l0 times around t e skirt 3, it has been discovered that a thinner, weaker or more readily fracturab'le sealing means, or less of .a sealin means of great strength, may be emplo e than when a single wra pin of the mem eris applied. This is possible ue to the fact as
